TROY, Mich. -- Police have announced they have Anthony LaCalamita, 38, in custody in connection with a workplace shooting Monday inside Gordon Advisors' Accounting Firm in Troy.

Police said a 50-year-old Dexter man driving a pickup truck on Interstate 75 near Flint and spotted the silver 2007 Ford Fusion for which police were searching and called 911.

"We knew who he was and what kind of car he was driving," Troy Police Lt. Gerry Scherlinck said. "Local police and state agencies were advised right away, and it appears we were successful in finding that car."

The Genessee County Sheriff's Department was en route to the Ford and became involved in a short chase with the driver, later confirmed to be LaCalamita. Officers followed the car through Saginaw and pulled him over in Bay City. They said they recovered a 12-gauge pump shotgun and three bullet shells from inside the car, according to Genessee County Sheriff Robert J. Pickell.

Pickell said LaCalamita was subdued when they finally caught up with him.

"When you're going at speeds up to 120 mph, and he's gone through some of that -- you can imagine right after that he felt like it was over," Pickell said of LaCalamita's body language.

The vehicle LaCalamita was driving was impounded and transported to the Troy Police Department, according to officials.

LaCalamita was processed at the Genessee County Jail and charged with fleeing and eluding police, but returned to the Troy Police Department later Monday afternoon. Police said he is expected to be charged with murder, among other charges.

LaCalamita entered the 1301 Long Lake Crossings building on Long Lake Road and opened fire on the second floor. Police and witnesses said that LaCalamita was a former employee of Gordon Advisors' Accounting Firm but was laid off last week.

One person has died and two more were injured, according to Troy police.

Police said LaCalamita seems to have chosen his victims carefully, shooting the first victim at the front of the suite, then charging toward the back and making eye contact with other employees until he allegedly found his two other targets.

In the first few moments following the shooting, no one knew if LaCalamita had escaped the building or was going to attack others inside the building. There are 40 other tenants in the same building and workers were were trapped in their offices, not wanting to leave for fear something would happen.

"All we heard was the screaming so we ran into a middle office -- our offices are all in one line -- we all ran into an office together and got under a desk," said Krista Partin, who works in the building.

Steve Johnston works on the second floor less than 100 feet from where the shots were fired.

"I just pulled everyone away from the reception area and made sure all the doors are locked," he said. "Then we sat there and waited for information."

A police swat team searched the building from room to room, starting on the ground floor and working their way up. Police said they slowly cleared sections of the building and escorted workers outside.

George Smrtka also works in the building and he said the incident is hard to fathom.

"Very surreal, you always see it on TV but never think it will ever happen where you work," Smrtka said.

The person killed was a 63-year-old woman from Warren, police said, but police wouldn't name the victim. A message posted this afternoon on Gordon Advisors' Web site said the office would be closed Tuesday in memory of Madeline Kafoury.

Police said the injured were Alan Steinberg, 48, of Sterling Heights, and Paul Riva, 48, of Bruce Township. They were rushed to Royal Oak's Beaumont Hospital because it is the only level one trauma center in Oakland County, officials said.

Hospital officials said they have both been in surgery. Families of the victims have requested privacy so no more information on their conditions will be released Monday.

Troy Police officers said they have obtained a search warrant for LaCalamita's apartment, and they said they hope the search will clue them in as to why he went on a shooting rampage. Neighbors said that he was quiet and they can't believe he would shoot anybody.

Rescue 4 has learned that his wife recently filed for divorce. Last week, police said LaCalamita applied for a concealed weapons permit but was denied.

LaCalamita will spend the night at the Troy Police Department and is expected to be arraigned on Tuesday.
